docs, bpf: Add minimal markup to address doc warning

Commit 91c960b005 ("bpf: Rename BPF_XADD and prepare to encode other
atomics in .imm") modified the BPF documentation, but missed some ReST
markup.

Hence, make htmldocs warns on Documentation/networking/filter.rst:1053:

  WARNING: Inline emphasis start-string without end-string.

Add some minimal markup to address this warning.
